Cardiac Electronic Implantable Devices in Elderly Australians: Results from GCOR

Abstract

Background: Elderly patients have traditionally had lower access to cardiac devices based partly on the perception that they experience more complications. They are underrepresented in clinical trials and limited data exist regarding the outcomes of elderly (>75 years) patients undergoing device implantation in Australia. Methods: The Genesis Cardiovascular Outcomes Registry (GCOR-Device) prospectively collected data on 5000 patients from December 2015-December 2018). This analysis compared patient demographic and procedural data with outcomes by age at implantation (≥75 years vs < 75 years). Results: Elderly patients received more single chamber devices 19.6% vs 10.3%, received less implantable cardioverter defibrillators 11.1% vs 23.3% and less cardiac resynchronisation devices 7.9% vs 11.0%. Elderly patients were more likely to be implanted during an inpatient stay rather than electively. The complication rates and type did not differ significantly between older and younger patients. Conclusion: Device implantation in elderly Australians produces complication rates comparable to those in younger patients.Tabled 1Outcomes at 1 year %>75 (n = 2634)≤75 (n = 2199)pMajor complications85 (3.1%)92 (3.9%)nsAll complications152 (5.3%)146 (5.5%)nsCardiac Readmissions117 (4.2%)46 (2.0%)<0.01Death125 (4.6%)23 (1.0%)<0.01 Open table in a new tab
